The present invention provides a process for recovering glycol from a process stream comprising glycol, water, dissolved salts, and hydrocarbons. The process comprises subjecting the process stream to a salt-enrichment process to obtain a salt-enriched stream having a salt concentration higher than salt concentration of the process stream, and a salt-reduced stream; subjecting the salt-enriched stream to a glycol reclaiming process to separate the salts and at least a portion of the hydrocarbons from the salt enriched stream to obtain a substantially salt-free water-glycol stream; and blending the salt reduced stream from the salt-enrichment process with the substantially salt-free stream to produce a reclaimed water-glycol stream

A distillation and desalination system can include a refrigeration unit, a distillation unit, and a vacuum source positioned in the refrigeration unit. The distillation unit may include a distillation chamber containing a saline liquid and a headspace above the saline liquid, the headspace comprising a gas. The vacuum source may include a first chamber defining a first chamber volume, where gas transport is permitted into and out of the first chamber and the first chamber is fluidically coupled to the headspace of the distillation unit, and a second chamber defining a second chamber volume, wherein the first chamber and the second chamber are fluidically isolated.

A method for separating a lubrication oil from a waste fluid includes separating water from the waste fluid by heating the waste fluid while sealed in a first vacuum chamber to a first temperature and first pressure. Fuel oil is separated from a fluid received from the first vacuum chamber by heating the fluid while sealed in a second vacuum chamber to a second temperature that is higher than the first temperature and at a second pressure. Finally, the lubrication oil is separated from a fluid received from the second vacuum chamber by heating the fluid received from the second vacuum chamber while sealed in a third vacuum chamber to a third temperature that is higher than the second temperature and at a third pressure.

In an example method, first electrical power is generated using one or more solar panels, and a water level rise of a sea is mitigated, at least in part, using a water processing system that is at least partially powered by the first electrical power. Mitigating the water level rise of the sea includes extracting saline water from the sea, desalinating the saline water, directing the desalinated water to one or more turbine generators, generating second electrical power using the one or more turbine generators, and directing the desalinated water from the one or more turbine generators into one or more aquifers. The one or more aquifers are hydraulically isolated from the sea.

One or more novel processes for producing hydrogen, oxygen, and in some cases, distilled and cleaned water from a contaminated effluent, are disclosed. In one example of utilizing this novel process, the water from contaminated effluent is transferred into a draw solution using an entrochemical system through a vapor-mediated membrane-free forward osmosis process. The process is enabled by the generation of a wet vacuum in one or more entrochemical cells incorporated into the entrochemical system. This process generates a diluted draw solution that can be utilized as an abundant water feedstock in an electrolyzer for electrolysis, which in turn generates hydrogen and oxygen. In some embodiments, an entrochemical distiller may also be utilized to distill a portion of the contaminated effluent for clean water as a result of thermal transfers during the vapor-mediated membrane-free forward osmosis process.

Techniques are described herein for using a high-pressure reactor to separate clean water from dirty water without filtration and to extract and concentrate contaminants from dirty water for use as a fuel. In particular, techniques and systems are described for separating water from hydrocarbon contaminates, other BTU-laden compounds, and dissolved minerals, while also boiling water and condensing the resulting steam into distilled water. In addition, system in which the described techniques are performed can be used as a high-pressure pump for moving the separated hydrocarbon contaminates forward into other processes, such as a high-pressure reactor or incinerator.

A distillation and desalination system can include a refrigeration unit and a vacuum source positioned in the refrigeration unit. The vacuum source can include a first chamber defining a first chamber volume, a second chamber defining a second chamber volume, a flexible diaphragm dividing the first chamber and the second chamber; and a check valve permitting gas transport into and out of the first chamber, the check valve comprising an inlet and an outlet. The system can also include a distillation unit having a distillation chamber, a saline liquid in the distillation chamber, and a headspace above the saline liquid, the headspace comprising a gas. The inlet of the check valve can be fluidically coupled to the headspace of the distillation unit.
